A few days ago I noted power in my estate was dim and being an electronics technician with basic knowledge in electricity I decided to visit my electricity meter to find out what is happening.
My meter is three phase and after checking other two lines, I noted they have more than normal voltage, actually 421 VAC instead of 240 VAC here in Kenya.
I logged on to our estate what’s-up group and broadcasted that power is abnormally high and therefore those with electrical equipment should disconnect them from the power outlet.
I received this Konka LED TV with the complaint of no signal symptom. The antenna jack was loosen once it was gently pushed by a screw driver (see the photo below) and this had caused the problem.
